4.) The following answers are provided in response to technical questions received:

1. QUESTION: Specification call for the metal wall panels to have a 3-coat Kynar finish. The 3 coat Kynar finish requires a large minimum quantity purchase due to manufacturing procedures. Will the Government consider a 2 coat Kynar finish in lieu of a 3-coat finish since the 2 coat finish is generally accepted in the industry?

ANSWER: Bid Schedule line item A0087 has been revised: Use 2 – coat Kynar finish.

ANSWER: Bid Schedule line items A0057, A0060, A0098, A0099, A0090, A0091, A0092, A0094, A0095 and A0097 have been revised, use minimum 140 mil thick base/interply SBS sheet, minimum 138 mil thick highly reflective SBS cap sheet, and minimum 180 mil thick granular coated SBS cap sheet as applicable.

4. QUESTION: Line Item A0075 is call for a vapor barrier referencing specification section 072216.23 Paragraph 2.4 and 2.7.1.

(1) There are two specifications Numbered 072216.23 page 384 & page 411 which specification should be used when pricing the project.

(2) 2.3.1 calls for a Type IV asphalt-impregnated felt, I assume this is the vapor barrier that needs to be priced for this section, (It is not 2.4 and 2.7.1), I also assume that any deck application needs to be considered.

(Concrete, Metal, Plywood, Tectum)

(3) 2.4 refers to adhesive, I assume that the vapor barrier needs to be fully adhered to the deck using this description.

(4) 2.7.1 is not in either specification section. I assume is needs to be deleted. Are these assumptions correct?

ANSWER:

(1) Use specification section 072216.23 beginning page 384. Delete specification section 072216.23 beginning page 411.

(2) Use Type IV asphalt-impregnated felt where called for as a vapor barrier and as recommended by manufacturer for concrete, metal, plywood, tectum, and cured gypsum decks.

(3) Fully secure vapor barrier to deck with adhesive as recommended by manufacturer for concrete, metal, plywood, tectum, and cured gypsum decks.

(4) Specifications have been revised to delete reference to Specification Section 072216.23 paragraph

2.7.1.

5. QUESTION: Line Item A0078 is referring to Asphalt Shingles the warranty in the specification is calling for a twenty Year NDL warranty, these type of warranty normally are in reference to Metal, TPO, BUR roofing not shingles. Is there a manufacturer's that you have used in the past that will offer this warranty, we are unaware of one. Normally shingle warranties refer the material not the weather tightness. The installer normally will offer a installer warranty. Please let me know how you wish me to offer this line item.

ANSWER: Bid Schedule line item A0078 has been revised: Provide manufacturer’s 10 year non-prorated warranty against defects. Provide manufacturer’s 15 year 130 MPH wind warranty. Provide Contractor’s one year warranty covering materials and workmanship.

6. QUESTION: Line Item A0085 is referring to underlayment under a metal roofing system (074113), but is requesting granular surface underlayment. It is standard roofing practice to not use a granular underlayment under a metal roofing system due to fact it can scratch the underside and cause rusting and material failure. We recommend a smooth or no granular surface material. Please advise.

(Please note that A0077 under the shingle roof is calling for a smooth surface underlayment, normally granular surface is used but smooth can be used as well, just an FYI)

ANSWER: Use manufacturer’s recommended smooth underlayment.

7. QUESTION: Line Item A0083 Concerning exposed fastener metal roofing system, the specification section it references is 074113, this specification section is designed and written around a concealed fastener roofing system. The first concern is the NDL Weather tightness, no manufacturer will offer a 20 year or NDL weather tightness warranty on exposed fastener. Do you wish to add additional specification section or are we to use the section 074113 and just ignore the things that do not apply.

ANSWER: Specification has been revised to delete requirement for manufacturers NDL weather tightness warranty. Use relevant portions of Specification Section 074113 and manufacturers recommended procedures and materials.

8. QUESTION: Line Item A0083 & A0084 Specification Section 074113 is requiring a Wind Uplift Rider (Page 461 1.9.1), I have contacted 3 National roof manufacturer's and none have heard of or know of anyone that offers a Wind rider. (Wind Riders can be offered or requested on TPO, BUR, EPDM, or PVC) If Patrick AFB has received Wind Riders on metal roofing in past can you tell us the Manufacturer that offers this rider.

ANSWER: Specification has been revised to delete requirement for Wind Uplift Rider for metal roofing as described on page 461 (paragraph 1.9.1) of the Specifications.

9. QUESTION: Line item A0120, B0120, C0120, D0120, & E0120 and line item A0121, B0121, C0121, D0121, & E0121 has 0 for the quantity. Line item A0136, B0136, C0136, D0136, & E0136 has the unit as SF. I think the unit should be an EA. Line item A0122, B0122, C0122, D0122 & E0122 are the same but different material and it is an EA. Please let me know.

ANSWER: Specification has been revised to delete Bid Item line number A0120 (AND OPTION YEARS) AND A0136 (AND OPTION YEARS). Change unit on A0136 (AND OPTION YEARS) to EA.

10. QUESTION: On the Bid Schedule, item A0064, section 07 22 16.22 Roof Board Insulation references SPEC: 07 22 16.22 paragraph 2.4 and 2.7.1. Paragraph 2.4 is in the SPEC, however 2.7.1 is NOT. Please advise.

ANSWER: Specification has been revised to delete reference to Specification Section 072216.22 paragraph 2.7.1.

ANSWER: Correct

12. QUESTION: Line 0087 is calling for 18 gauge aluminum-zinc per delivery order 200 sqft.

(1) The manufacturers are telling me there is a minimum sqft 5,000 sqft to 6,000 sqft per order Please advise.

(2) (074213 Page 495, 2.1.3) 3 coat finish is high in and very expensive, 2 coat is normal and easier to get. Is 2 coat acceptable?

(3) (074213 page 494, 1.10) 20 NDL Warranty is not normally offered on wall panels, if a manufacturer is currently offering 20 NDL on 18 gauge wall panels please advise to which is offering this.

(4) (074213 Page 2.1.2) "Profile gauge thickness and depth indicated" The Line 0087 & 0088 indicates 18 gauge but no profile is mentioned. This is very important to the price and availability of the product.
